Considering soil protection as an integral part of the agro-system, a multi-disciplinary research team of the Office de la Recherche Scientifique et Technique Outre-Mer (ORSTOM) and Groupement d'Estudes et de Recherches pour le Development de l'Agronomie Tropicale (GERDAT) have been studying for five years biological techniques (various crop residue management and tillage systems) to reduce soil erosion and nutrient waste by leaching. Some practical conclusions can be drawn from the numerous data collected on plots under natural and artificial rainfall and on blocks of two major plantations. aAbacaxi aAnanás Comosus aDoença aErosão aNematóide aSolo1 aROOSE, E.
